Lake Rocky should really be known by its Japanese name, Rocky's Sea, as it it not a lake at all. But this incongruity aside, the stage is the fourth level in Tails Adventure for the Sega Game Gear, coming after Polly Mountain 1 and before Cavern Island. Though thanks to the non-linear nature of Tails Adventure, Tails must return to the region on various occasions as new items (like the Anti-Air Missile and Mine) open up new routes.
Having acquired the Vulcan Gun component from the Kukku army on Polly Mountain 1, Tails is finally able to bring the Sea Fox submarine up to combat readiness. Now the outlying islets off the coast of Cocoa Island proper can be explored. Launching off from the pier outside Tails' House, Tails can take to the waves; although predictably the Kukkus will arrive there first.
"Lake" Rocky is a coastal shoreline riddled with underwater caverns - and no shortage of mines, which are dropped all over the place by the airborne invaders. In his first visit to the level, Tails simply sails right through to Cavern Island, but there are numerous different navigational routes leading to different offshore areas. The seawater turns eutropified viridian around the entrance to Lake Crystal, and the downwards path leading to Coco Island is crammed full of guns and mine chutes.
There are no items available in Lake Rocky.
